 be wholly unconnected with each other. I shall undertake in the next place to show, that unless these departments be so far connected and blended, as to give to each a constitutional control over the others, the degree of separation which the maxim requires, as essential to a free Government, can never in practice be duly maintained.

It is agreed on all sides, that the powers properly belonging to one of the departments ought not to be directly and completely administered by either of the other departments. It is equally evident, that none of them ought to possess, directly or indirectly, an overruling influence over the others in the administration of their respective powers. It will not be denied, that power is of an encroaching nature, and that it ought to be effectually restrained from passing the limits assigned to it. After discriminating, therefore, in theory, the several classes of power as they may in their nature be Legislative, Executive, or Judiciary, the next and most difficult task is to provide some practical security for each, against the invasion of the others. What this security ought to be, is the great problem to be solved.

Will it be sufficient to mark, with precision, the boundaries of these departments, in the constitution of the Government, and to trust to these parchment barriers against the encroaching spirit of power? This is the security which appears to have been principally relied on by the compilers of most of the American Constitutions. But experience assures us, that the efficacy of the provision has been greatly overrated; and that some more adequate defence is indispensably necessary for the more feeble, against the more powerful, members of the Government. The Legislative department is everywhere extending the sphere of its activity, and drawing all power into its impetuous vortex.
